My little sister got one of these for XMas. For some reason I cannot get it to sync up correctly. Anyone use these?

1) When I plug it in to the USB, the device does not pop up as an active device (notheing comes up). I tried Restarting Computer, different USB drives.

2) The couple times I got the device to be recognized, I could not get it to sync my books to my device.

Any help would be great. I am gonna reinstall the Desktop App, and try that. Otherwise I am out of ideas.
